Doc's Diesel 6.0L Ford Fuel Filter — Fits F-250/F-350/F-450/F-550 2003–2007, 3‑Micron Water-Separating OE Fit

Doc's Diesel Fuel Filter is a direct-fit replacement for Ford 6.0L Super Duty trucks (2003–2007) that removes water and particles down to 3 microns with independent 96.92% efficiency.

If you drive a 6.0L Ford F-250, F-350, F-450, F-550, Excursion (2003–2005), F650 or F750 (2004–2008), this fuel filter is built to match OE fitment and protect fuel-system components by trapping rust, dirt and separated water before they reach injectors and pumps. The filter has been third-party tested so the particle-capture rating is verified rather than claimed. Follow your vehicle manufacturer’s service intervals—commonly every 5,000–10,000 miles—for reliable performance.

How does this filter protect my 6.0L Ford on long drives?

The filter captures abrasive particles and removes separated water before fuel reaches sensitive components, reducing wear and the chance of fuel-system blockages. Cleaner fuel helps maintain consistent injector and pump performance under load.

• Third-party tested 3-micron efficiency at 96.92%.

How often should I replace this fuel filter on my 6.0L diesel?

Service intervals vary by driving conditions and warranty guidance, but a common recommendation is replacement every 5,000–10,000 miles, with 15,000 miles as an upper limit under benign conditions. Inspect filters more frequently if you encounter poor fuel quality, contamination, or heavy-duty use.

• Replace per vehicle manufacturer warranty requirements.
